Toyota has disclosed full details for its IAA-bound Yaris Hybrid-R concept scheduled to get its public outing next week.

Based on the three-door Yaris, the Hybrid-R concept comes with a four-cylinder 1.6-liter turbocharged engine delivering 300 bhp (224 kW) and 420 Nm (310 lb-ft) to the front wheels, while each rear wheel is driven by a 60 bhp (45 kW) electric motor. The two electric motors have a combined maximum output of 120 bhp (89 Nm) available for up to five seconds when Track mode is activated. During this five-second interval, the concept has a maximum output of 420 bhp (313 kW).

There's also a third 60 bhp electric motor installed between the conventional power unit and the six-speed sequential gearbox. It works during deceleration to feed the super capacitor and also during acceleration to power the two rear electric motors, but only when the power and torque of the engine exceed the grip potential of the front wheels. In other words, the generator will act as a traction control system redirecting torque as electric energy to the rear axle.

The Toyota Yaris Hybrid-R has been fitted with 18-inch TRD alloys wrapped around in Michelin Pilot Sport Cup tires measuring 225/40 R18 with stopping power coming from grooved and perforated discs that have six-piston calipers at the front and four-piston calipers for the rear.

The cabin comes with GT 86-sourced sport pedals, dual-tone Recaro bucket seats with black leather side bolsters and blue Alcantara. The shift lever has been positioned close to the driver's right hand, while the sport steering wheel is covered in Alcantara.

Aside from the aforementioned Track mode, by pressing a button installed on the steering wheel the driver can select Road mode which will reduce the output of the gasoline engine and manage the quantity of energy distributed as a method to reduce fuel consumption and cut down CO2 emissions.
